Sewage Treatment Aeration Roots Blower Affordable Vacuum Pump

Product Description

Product DescriptionOur HDSR series vacuum pump is developed based on the introduction of RR series fan technology from Japan using our company's countercurrent cooling patent technology. The vacuum pump is used for absorbing high vacuum. Countercurrent cooling is a kind of cooling method that uses low-temperature gas as pre-intake gas and usually sets the pressure of cooling gas to be equal to the exhaust pressure.

Our Advantages(1) High vacuum pressure roots type blower, much higher than common roots vacuum pumps.
(2) Air cooling, don't need water cooling system even at high vacuum pressure.
(3) Advanced structure design, low vibration and noise level.
(4) Positive displacement structure, flow rate changes little even pressure changes.
(5) Long service life term, more than 10 years under the guidance.
(6) Adopt a number of patent technologies such as countercurrent device, advanced and reasonable structural design.
(7) The impeller adopts a specially designed composite line with high efficiency.
(8) The processing precision of key parts is high to ensure the smooth operation of the vacuum pump
(9) High vacuum, wide flow coverage
ApplicationRoots vacuum pump in petroleum, chemical industry, plastics, pesticides, steam turbine rotor dynamic balance, aerospace space simulation and other devices have been tested for a long time, so it should be vigorously promoted and applied all around the world. It is also widely used in petroleum, chemical, metallurgy, textile and other industries. Vacuum pump accessories as a vacuum pump silencer, used for vacuum pump noise control.
Vacuum packing, metallurgy, deaeration, rolling in vacuum metallurgy, and vacuum distillation, vacuum concentration, vacuum drying in chemicals/food/pharmaceutical/wastewater treatment industry, pneumatic conveying system, paper folding system, etc.
